The 7200 5 mm and 8 mm Proximity
Transducer Systems are noncontacting,
gap-to-voltage transducer systems that
measure static as well as dynamic distances between the probe tip and the
observed target. The general application
is any requirement for an accurate, noncontacting displacement measurement.
However, the most common use is for
shaft position and vibration measurements on rotating and reciprocating
machinery.They are designed for use
with virtually any machine type including gas and steam turbines, compressors,
pumps, centrifuges, electric motors and
generators. The systems offer 80 mils
(2 mm) of linear measuring range and
are compatible with API 670
requirements.
A system consists of a probe with integral coaxial cable, an extension cable,
and Proximitor®. All 7200 proximity
transducer systems are compatible with
3300 and 9000 Monitoring Systems.
Applications
The 7200 5 and 8 mm Systems have
a frequency response of 0 Hz (DC) to
10 kHz and can be used to make the
following types of measurements:
• Radial vibration for indicating
bearing condition and such machine
malfunctions as rotor imbalance and
misalignment.
• Axial thrust position for
determining thrust bearing wear or
potential bearing failure.
• Shaft average radial position, for
determining attitude angle, an indicator
of rotor stability.
• Vibration amplitude and phase
angle for plotting diagnostic information
in Polar and Bode formats.
• Eccentricity to measure the
amount of rotor bow.
